Assignment 2 Introduction to Econometrics STATA OUTPUT – For a The sample mean for beauty ratings is -0.0109287, as shown from the output. STATA OUTPUT – Q b The regression output predicts course evaluation using beauty, with beauty being the independent variable while the course evaluation is the dependent variable. From the output the null hypothesis from the F-test is that the R-squared is 0, but the F-test value is 0.0085 which is less than 0.05, therefore we reject the null hypothesis with 95% level of confidence. The R-squared, 0.0197 shows that the model explains only 1.97% of the variation in course evaluation is explained by the model, because the model does not explain...

Problem 1 Question 1The determination of the median height can be arrived at by taking the functional value of f (48). The value x should be substituted for 48. This should look like follows: F(48)= 3.1√(48)+19 =3.1(6.928)+19 =21.47+19 =40.5 Question 2 The calculation obtained above indicates a median height of 40.5 inches. However, the actual height is said to be 40.2 inches. The meaning of this analysis is that the model has overestimated the height by the difference of 40.5-40.2 which is 0.3 inches. Question 3 It is appropriate to determine the height of the girl during birth, considered as month zero. Once this has been achieved, it is good to substitute 0 in place of x. The function looks like...
problem is that we cannot change the vegans and vegetarians notion towards meat. Most of them avoid eating meat too because they believe they will get sick or because they do not like its tastes. Unless we have a solution to that problem, lab-grown meat may not be as effective as we...
